ABSTRACT

A class of exact solutions of the equations of the dynamics of a rotating stratified liquid, describing finite-amplitude axisymmetrical waves in a cylindrical layer is obtained. The gravity force in this class of solutions is represented by centripetal acceleration. The pertinent dispersion equations are obtained. An analog of these waves in the dynamics of a homogeneous rotating liquid is also analyzed and its relationship with the Batchelor wave solution is established.
